ANTHOZOA. 273 



cycle standing next those of the first and second cycles are longer 

 than the other members of the fifth cycle; the upper margins of 

 the first and second considerably elevated, those of the third less 

 so. Calice rather deep. Columella lax, spongy, not greatly de- 

 veloped. (Adapted from Vaughan.) 



The dimensions of two nearly complete coralla are: greatest 

 diameter of calice, 22.5 mm. and 16 mm.; lesser diameter of 

 calice, 15.5 mm. and 13 mm.; height of corallum, 40+ mm. and 



33 mm - 



Remarks. This species is the commonest one of the corals in 

 the fauna of the Manasquan marl, and may sometimes be col- 

 lected in great numbers upon the marl heaps near Farmingdale. 

 It may be easily distinguished from Trochocyathus conoides by 

 its finer costse and by its curvature in the plane of the longer axis 

 of the calice. 



Formation and locality. Manasquan marl, near Farmingdale 

 (138), near New Egypt (155). 



Geographic distribution. New Jersey.
